I/O hole detecting machine platform

Abstract

The invention discloses an I / O hole detecting machine platform mainly comprising a base and a working platform. The working platform is arranged on the base, guiding rails and a lead screw mechanism are arranged between the base and working platform. A motor is connected with the tail end of a lead screw, and the controlling end of the motor is connected with the signal feedback end of a controlling program. The I / O detecting machine platform is characterized in that L-shaped supporting bases are both arranged on the outer sides of the two guiding rails on the base and perpendicular to the extending direction of the guiding rails. Detecting devices on the L-shaped supporting bases comprise charge coupled device (CCD) imaging devices, camera lenses and light sources. The camera lenses penetrate positioning holes on the side edges of the L-shaped supporting bases. The two ends of each camera lens are respectively connected with one CCD imaging device and one light source. A zero degree is formed between the center axis of one camera lens and a level surface, wherein in the other arranged detecting device arranged on one L-shaped supporting base at one side, an included angle is formed between a center axis of the camera lens and the level surface and in range from zero degree to 45 degrees. By utilizing the CCD imaging devices, sizes and location degrees of holes to be detected in products are obtained, status of profile tolerance of square-shaped holes in the products is obtained, pass-through rate of the holes to be detected are obtained and the holes are checked to be got through or blocked by impurities.

Description

technical field [0001] The invention relates to an I / O hole detection machine, in particular to an accurate and efficient I / O hole detection machine. Background technique [0002] Due to the needs of external interfaces on the housing of electronic products, according to the design requirements, there are usually a number of holes for the passage of external devices on the housing. In order to ensure its quality, it is usually necessary to detect the size and position of the holes, as well as the contour of the corresponding square holes. . In order to realize automatic detection, the combination of CCD imaging technology and control program is usually used to issue action instructions through the control program to control the product to be inspected to move to the corresponding position, use CCD technology to affect the part of the scene to be inspected, and use software to process data for the viewfinder image. In this way, the pixels of the learned part are obtained, an...

But for slender holes, if it is detected whether it is blocked by impurities or not opened, it is necessary to manually detect or calculate the permeability of the hole through the program according to the image, and the permeability is the actual through hole area and The ratio of the theoretical through-hole area, the detection efficiency is greatly reduced by the above method
